- Another tip on how to set up 4WS with Drive Modes on the Radiomaster MT12! Buckle up, because we are getting pretty technical with this one... Feel free to pause or slow the video down. Also feel free to ask a question in the comments below!
Note, if you need to trim or reverse a servo, I suggest doing so in the Outputs screen and leaving the Mixes alone.
Another note, instead of turning the Global Var into an Input and then using that Input as a multiplier in the Mixes, you can also directly use a Global Var as the weight in the Mixes tab. I recently re-learned that after making and posting this video... Let me know if you want to see an update to this video with that method of setup instead.
As you may be able to hear, I also added Special Functions to play audio files for the different modes, but, I didn't go over how to do that. Originally I wanted to wait until there were official sounds to post directions on how to do that. I've opened a request with the Official EdgeTX Sounds team to add the sounds there, but until then, here is a GitHub link for the audio files I made:
github.com/jakezilla/FourWhee...
Add those sounds to your SD Card and add Special Functions to play the tracks when your Drive Mode is active.
Here is my request on the official EdgeTX Sound GitHub; you can keep an eye on that and see if/when the sounds are added:

THANK YOU, i would never do this on my own
This is a really helpful video thanks. Only issue I’m having is T4 isn’t switching the Drive modes other than 0 to 1…. L10,11 & 12 switch, but DM stays at DM1 🤷🏼♂️. Other than that I think I’ve got the rest sorted
Glad the video was helpful! Did you copy the order correctly? If multiple logical switches are on at the same time, it will choose the lowest drive mode. I tried to explain this at 4:55 but maybe it wasn't clear.
@@JacobScherer in the end I started from a fresh 'model'. I must have changed something while playing around with the servo mixes before trying this. Now works perfectly. I'd never have managed it without this video though! Big thanks, I now have a 10x10 with 4 modes of steering :)
Wow this is a big help now that I have studied it for a week. It’s a lot to get used to but I am liking my M12 more and more.
Thanks for making this video and others about this radio. I have the ELRS version and no prior experience with Edge TX, so the learning curve has been wavy at best. This video helped cure another setup issue I was having. Much appreciated sir, any other setup tips even basic ones would go a long way for folks who are new to this system
Thank you for your comment!
Thank you very much that all worked. Now do I have to set up a separate trim switch in order to trim the rear servo to straighten it out a bit?
This Video is awesome I have my Ax 24 all programmed up this way I do have 1 question though is it possible to add trim to the rear steering so you can trim it like the front wheels.
I would trim the rear steer channel in the outputs tab. If you want to try and assign a trim switches to it, it gets real complicated...
@@JacobScherer ok perfect the rear steering channel is channel 3 so i think all i need to do is assign the trim switch to the channel
lets say we use switch (SC) as a toggle between the different drive modes, using an edge logical switch, .5 sec press is mirror steer, 1-2 sec press is rear steer, and 2-3 sec press is crab steer.
my problem is that it doesn't "toggle" it,i have to set a duration, and i have to wait for said "duration" to pass before i can toggle another mode....
i wonder if i can use the sticky function... how would you go about it?
Thanks 4 the great video.. Can you please share the model YAML file?
and how do you get your transmitter to voice the drive modes? I have every audio setting on that i can find.
❤parrallel your battery supply so both escs have the same voltage
How did you get it to announce the steering modes ????
how can I set on of the dials to override them all modes or make a mode on the trim so I can manual use the rear?
Same question
It's funny I was thinking " mirror" also then it dawned on me... it just simply 4WS. Thanks a ton for making the video
I watched your video and @donoldsneffe video on 4WS.
Both were helpful ❤
I believe in real life use the
SA switch would be superior for ease of use
Down = FWS
Middle = 4WS
Up = crab
And drivers choice of P2 or P1 for rear steering.
I haven't figured out how to make the crab happen yet 😂
And right now I can rear steer with P2 but only if I'm in the SA middle position
Any thoughts?
Call me pedantic, but to me they are all 4ws, lol
Can that controller graph any calculus or differential equations? Asking for an engineering friend....
It actually can!
Wow! Respect! ;-)
Guess your "Mirror steering" is simply called 4WS ;-) - at least I/we call it that way.
But calling it 4WS is so boring compared to the cool "Crab Mode" haha.
@@JacobScherer after watching your video 4 times I will try to reproduce this now on my MT12 (of course while watching and pausing the video) - pfff, that is unbelievably complex.
@@donaldsneffe yes, very complex. With some different choices for switches and some software work to match existing surface radio features, this would be a much better system.
@@JacobScherer Agree totally.
Most people in our forum are completely overstrained with this (many do already have problems with simple radios such as NB4, GT5, RC8X, Dumbo etc.).
More switches would be highly desirable, too. Donno why there is no push button "in" the handle, or two - what nearly all pistol grip radios do have. The switch below the "trim" switch is very inconvenient, strange to use...
My only question is to get my remote to announce what mode it’s in like yours does , mirror , front , rear , crab I’d like my remote to say that
You would set that up in special functions to play a track when the mode is active.
